煤矿开采区水、土地与煤炭资源同步利用模式研究
,庄健鸿
资源科学 , 2007,
Abstract: 21世纪我国的资源紧张局面将进一步加剧,影响可持续发展战略的实施和全面建设小康社会目标的实现。我国煤矿开采区水、土地与煤炭资源互耗问题严重,煤炭资源的开采导致地下水污染、土地沉陷或淹没等资源浪费和生态环境破坏问题。本文在分析资源互耗矛盾的产生机理的基础上,提出水、土地与煤炭的资源同步利用理念及其应用基础,同时,指出实现资源同步利用的关键在于找到各种资源利用的最优临界值。最后,结合南水北调东线工程南四湖流域的资源利用现状和调水工程特点,初步探讨该地区的资源同步利用的实现模式:①管道分级的输水方案;②将采煤沉陷区的地下水纳入南水北调工程的水量调蓄管理系统;③恢复南四湖流域沉陷区的土地功能。

Abstract: 本文以国家农业科技攻关南皮试区为例,分析了华北缺水盐渍区地下水水位动态豚其与降水量的关系,应用灰色系统理论的GM(1,1)预测方法,建立了地下水位动态的模拟,预测模型。结果表明,在目前供水,用水和水文地质条件下,未来地下水水位呈缓慢下降趋势,年均下降速度为0.12-0.14m/年,单靠平水年甚或丰水年降水难以维持地下水采补平衡。必须进行多年径流调节或跨流域调水,以丰补歉,互济余缺,并实施农田综合节水技术,防止区域水环境的恶化。

Abstract: 鄂尔多斯遗鸥自然保护区属于典型的半干旱区高原内陆湖泊湿地,地下水是其重要水源之一。本文以遗鸥湿地所在的泊江海子流域为研究对象,系统分析了地层岩性、含水系统及富水性、地下水流场特征、地下水水化学特征等基础水文地质条件,并计算了地下水系统的水均衡。结果表明:泊江海子流域主要有松散岩类孔隙含水层和碎屑岩类孔隙裂隙含水层,松散岩类孔隙地下水严格受闭流盆地地形条件控制;碎屑岩类孔隙裂隙地下水主要受区域地形及水文系统控制;大气降水补给和侧向径流补给是泊江海子流域地下水的主要补给源,两者约占总补给量的85%,而潜水蒸发和人工开采是地下水的主要排泄方式,约占整个系统排泄量的89%,1996年-2005年,泊江海子流域地下水总的年均补给量为6358.9×104m3/a,总排泄量为7418.2×104m3/a,地下水均衡差为-1059.3×104m3/a;桃-阿海子接受的地下水补给量约为142.5×104m3/a,占桃-阿海子湖泊总补给量的22%,是桃-阿海子湖泊的一个重要的补给来源。

Abstract: 地下水环境承载力是水环境承载力研究的重要组成部分,是衡量人类社会经济发展与区域水环境协调程度的判别依据。以内蒙古自治区准格尔旗为研究区,建立地下水环境承载力评价体系,并利用层次分析法(ahp)判断矩阵确定各指标的权重值,进行研究区地下水环境承载力评价。结果表明,准格尔旗地区地下水环境承载力在0.3083~0.7311之间,平均为0.5215,属于中等偏弱程度。评价结果与研究区水文地质条件和社会经济发展现状基本吻合,可为准格尔旗在未来工业化进程中地下水资源管理和地下水环境保护决策提供依据。

Abstract: 为研究在全球气温变暖条件下以马海盆地为代表的青藏高原北缘地区的气候变化特征,运用累积距平法、mann2kendall检验法、小波分析法对马海盆地的年降水量和年平均气温时间序列变化进行了多周期分析。研究表明,1970年-2010年马海盆地年降水量基本处于稳定状态,而年均气温有升高的趋势;在2001年之前,马海盆地降水呈减少的趋势,之后降水有增多的趋势,而年均气温在1995年之前呈现下降的趋势,之后开始回升;这一地区降水量变化震荡周期主要为15a、30a,气温变化则以26a为主周期;研究区降水和气温在不同的时间尺度上经历了不同的多2少及冷2暖的循环变化过程。对于不同的尺度周期,同一时段的降水量、气温变化会有所不同,时间尺度越小,气温、降水变化位相差异越小。
The Study for Groundwater Resources System of China with Three-rated Appraising Method of Sub Area
中国地下水资源系统三级分区及其在海河流域的应用

Abstract: 地表水与地下水是水资源系统中的两个重要组成部分,由于水体在地表与地下介质中的运移和储存方式不同,在水资源评价中所采用的模型和计算方法各异。中国第一轮水资源评价中,仅全国地下水资源总量一项,不同部门评价计算的结果年资源总量差达1000×108m3/a1](占全国地下水资源总量的1/8左右),这个数据相当于中国正在组织实施的南水北调工程的总调水量的一倍以上。作者认为在中国第一轮水资源评价中,地表水采用流域分区进行评价,地下水则采用水文地质单元的分区方法进行评价,是引起中国水资源总量误差问题的根本原因。由于自然界的四水转化关系十分复杂,分别采用地表水流域评价法或水文地质单元评价法,都无法避免水资源总量评价的误差问题。论文通过研究提出中国水资源三级评价分区方案,在地下水资源量评价中采用一二级按流域分区与地表水系统取得一致,三级按地下水单元分区的方法,解决中国新一轮水资源评价的误差问题。

Abstract: Water,land and coal resources are of great significance for economic booming and social stability of China in the 21st Century.However,in the coal mining area,there exists a complex relation among water,land and coalmine which lead to water and land resources are wasted because of coal exploitation.On one hand,coal mining can damage groundwater circulating system,induce groundwater contamination and land subsidence of large area.On the other hand,groundwater can flood coalmine and land,which disturbs coal exploitation work and makes existing land use lost or changed.Based on the analysis of the relations among three resources,this paper put forward a new concept of "resources sync-utilization",which suggests that rational utilization of some kind of resources mutually interacting can make best use of all kinds of resources.We classify "resources sync-utilization" in coal mining area into two types,the period of mining and the period of mine closure.The key to the success of former resources sync-utilization lies in appropriate coal mining technique and rational mining ratio,and that of the latter one is rational utilization of water resource.In order to further explain how to realize "resources sync-utilization",we take an example of Nan'si Lake Basin in Shandong, located in the influence area of South to North Water Diversion Project(East Route),the present severe land subisdence and flood caused by coal mining will become worsen because of the diversion of water.So three suggestions is given in order to archive the goal of "resources sync-utilization" in Nan'si Lake Basin: 1) water transfer scheme by multi-stage conduit pipe;2) contain groundwater in the subsidence area in the running of water quantity management system of South to North Water Diversion Project;3)recover the land use by pumping shallow-aquifer groundwater.The study on sync-utilization mode of water,land and coal resources should be dominant research direction in the future China,especially in the plain coal mining area,which will be an effective method for solving the problem of resources shortage.Moreover,mine water is a potential groundwater resource whose value has not been recognized yet,but has a good prospect of application.

Abstract: The study on impact of urbanization on groundwater recharge has a very important significance, not only for studying the hydrologic cycle, supply-demand balance, groundwater overexploitation, but also for preventing and controlling the deterioration of groundwater quality, and for revealing the organic relation between overexploitation and water quality deterioration, the two main problems of groundwater environment. However, up to now, it has not been determined weather the urbanization development would result in the increase or decrease of groundwater recharge, and the impact mechanism of urbanization on groundwater recharge also has not been illustrated. The study on the interaction mechanism of urbanization and groundwater in Shijiazhuang City is a typical example. In this paper, based on the analysis of the importance of groundwater in water supply of the city, and the exploitation and utilization of groundwater, the authors studied the change of groundwater recharge under the impact of urbanization, and further discussed the impact mechanism of urbanization on groundwater recharge. Finally, a frame-figure on the mechanism inducing the increment of groundwater recharge was constructed. The results show: 1) urbanization results in the increase of groundwater recharge; 2) the inducing of groundwater from the well-field around city and surface water by exploitation of groundwater, and the importing of new recharge sources resulting from the leakage of water-supply and water-discharge systems of city, is the important mechanism inducing the recharge increase of groundwater by urbanization; 3) the new recharge sources resulting from the leakage of water-supply and water-discharge systems are one of the important components which should be considered fully in the calculation of groundwater recharge in the urban districts. This study supplies a kind of theory and new approach to study hydrological cycle and water resources in the urban districts.
